SPECIFICATION forming part of Letters Patent No. 657,478, datedSeptember 4, 1900.

Application filed June 30, I898 To all whom it may concern.-

Be itknow'n that I, THADDEUSOAHILL, a citizen of the United States,residing at Washington, in the District of Columbia, have in vented.certain new and useful Improvements' in Type- Writing Machines,Linotype-Machines, Type Sjetting Machines, or other Keyboard PrintingInstrumentalities, of which the following is a specification.

Certain features of my invention are designed for use in typefwritingmachines, linotype-machines, type-setting. machines, and other keyboardprinting instrumentalities in which letters are produced (printed orselected) by operating upon keys, while. other features of my inventionare peculiar to type-writing machines. I shall first describemyinvention as applied to a type-writing machine and will then point outhow certain important features of my invention may be applied tolinotype-machines, typesetting machines, and other keyboard printinginstrumentalities.

As applied to a type-writing machine the objects of my invention are tomake a typewriting machine in which the operator can depress a pluralityof keys in succession to make successive letters without having torelease the key first depressed befored'epressing the next key.Intype-writing machines as ordinarily constructed it is necessary, itshould be understood, to release one key before another key can bedepressed to make another letter. This necessitatesan abrupt or staccatotouch on the part of the operator in which each movement is made by initself. In playing apianaforte, on theother hand, or an organ with theusual legato touch there is none of this abruptness. One movementoverlaps another. The finger which has just depressed a key is risingwhile another finger is depressing another key to produce the next note.By reason of this overlapping of the movements this fact that severalmovements in difierent phases are taking place at the sameLime-performers can play scales and produce other effects on apianoforte, as is well known, with the most remarkable rapidity. Thetouch in which one movement overlaps another, in which one key begins toSerial No; 684,880. (Np modal.)

descend before the preceding key has been released, is commonly termedby musicians (forreasons which Ineed not go into here) the legato-touch.A principal object of mypresent invention is toenable the operator touse a legato or overlapping touch in depressing the keys of atype-writer--that is to say, to depress a key before he has released orwhile he is releasing the last key depressed-and to obtain properprinting. By doing this I make the operating easier and more natural andat the same time materially increase the speed, for in type-writingmachines as ordinarily constructed the limit of rapidity of action isthe time in which the operator can both depress and release the key,while by my invention the limit of rapidity of action is the time inwhich the operator can depress the key. He does not need to release itbefore he depresses another.

The features of my invention above referred to by which the operator isenabled to depress a key without waiting to release the key or keyspreviously depressed may be applied to type-setting andlinotype-machines as well as to type-Writing machines. The remainingfeatures of my invention are specially applicable to type-writingmachines; and it consists in certain features of constructionhereinafter described by which a typewriting machine of simple anddurable constru'ction is made adapted to Write letters one at a time andhaving a few keys acting singly and in different combinations to controla much larger number of characters.

I shall first describe a novel form of typewriting machine (illustratedin Figures 1 to .14. of the accompanying drawings) in which my inventionis embodied. After that I shall illustrate certain features ofmyinvention as applied to certain other forms of type-writing 9omachines. Then I shall illustrate the application of my invention to alinotype-machine, and, finally, I shall point out and specifically claimthe parts, improvements, and combinations in which the inventionconsists.

The machine illustrated iu.Figs.. l to 1'4, i'nclusive, resemblesin manyways the machine. illustrated in a pending application. of mine, SerialNo. 668,737, filed February 1,1898; but

the machineill nstrated inFigs. 1 to; 14 of? thepresent application.d-ilfers from the machine illustrated inthe pending application.beforesaid, (a); in that it" is constructed to write l'ett'ersone' at atime only, while the machine illustrated'in the applicationof'F'ebrua'ry 1, 1898, aforesaid is adapted". to write" letter-sin pairs,(6) in that it i's'c'onstructe'd toenable' the operator to-depress' akey to makea letter without having first to release the" key or'keysd'epressed to make the preceding, letter, and ("c) in various otherparticulars, the most important of are pointed out in the statement ofclaim atthe end'hereof'.

The machine shown in Figs. 1,t014 of the accompanying drawings inillustration of my inventionconsists, essentially, of (a) a set of ltypeebarslsuitably-mountedand sttil-ing to a 1 trolled; by said; keysactingsin glyand in diffene.nt,-combinations,,whereby the type-barsaforesaid are connected,each as required, with the motor deviceaforesaid and said motor idevice. brought into action to impel thet'ype-'fbar' thus connected with it; (a) means con- :nectedwith andi actuatedbythemotor, de- .viceafo'resaid,,whereby said motor device as the.type-bar. approaches.v the printing point' c uts;off" the power from, it's'elf'an d" releases the lvario'us'parts.controlled by the key, sothat the type-bar'witli; the; other parts controlled ghy thekey,inc1'uding the motor device itself, *can resume. their normal"positions, whereby the operator is enabled to" depress another key'tomakeanotjher letter without having ?to wait torel'ea'se the lieyfirstdepressed, and (f)'a-paper'-carriage, spacing mechani'sm,rib-

Ebon mechanism, and other usual devices,

iwhich beingoldand' well known l need not Themathframe-The main frame ofthe gin'a'chinezfi'gured in the drawings consists, es- ;jsentiall'y', of(11) a bed pl'ate 1', ('b)'a top plate ,2, (1c).a center ring 4'0, (d)standards 41 41', bolted to" the bed-plate andservin g to support thecenter ringylJO, the group-controlling l'evers; the bell-crank levers,the motor-frame, the circnitclosing] frame, the pin carrierdrivingfi'ame the normal frame, and'various other parts hereinafterdescribed,,and(e)' four coin urns 424242 42', which rise from the center ri'ng'tOto support the t0p'plate2;

The type-Bars and'the meansfor controlling .them.--50i50' are thetype-bars mounted" by 'means of hangers'5'1 51 in the usual fashion. -Afew type-bars only are shown in the drawings, but any convenient numbermay of coursebe used. The machine figu'retl in the Underneath the innerends of' the radial] IIO levers 52 52 are the pins 60, (one pin to everyfour radial levers as the machine illustrated in the drawings isconstructed,) mounted in the oscillating pin-carrier 61 and held intheir normal positions (shown in Figs 1, 2, and 12) by light expansivesprings 62 62, which bear upon collars 63 63, attached to the pins 6060, forcing said collars down on the lower disk of the pin-carrier. Eachof the pins 60 60 serves to give movement to the different radial leversof the group controlled by it, each as required, the pin-carrier 61being oscillatedto bring the pins into operative relation with thedifferent radial levers controlled by them, each as required.

Just below the pins 60 60 are the groupcontrolling levers 65 65, whichare centered on rods 66 66, supported in the standards 4141, saidstandards being milled to produce slots to receive the severalgroup-controlling levers aforesaid. The proximate ends of thegroup-controlling levers 65 65 are made segmental, as illustratedinFigs. 5 and 8, so that however the pin-carrier 61 may be vibrated eachof the pins 60 6O always lies over the corresponding group-controllinglever 65. Tilting pieces 67 67 are hinged to the groupcontrollinglevers65 65. An oscillating frame 70 underlies said tilting pieces. Saidoscillating frame is mounted by means of the arm 71 of the rock-shaft 72and a bridle-lever 73, to both of which it is pin-jointed. To the otherarm 74 of the rock-shaft 72 the armature 75 is connected. Said armature75 and the core 76 (which is attached to a plate 77, that is bolted tothe bottom of the bed-plate 1) lie within a non ferruginous tube 78,around which the energizing-coil 79 is wound. The magnet thus formedserves to give movement to the oscillating frame 70 aforesaid, andthereby'to whatever one of the groupcontrolling levers 65 65 may haveits tilting piece 67 67 overlying said frame. A tilting piece 67, hingedto one of the group-control- I ling levers 65, normally overlies themotorframe 70, while all the other tilting pieces 67 67 lie out of thepath of movement of said oscillating motor-frame.

We have seen that each of the group-controlling levers 65 65, with thecorresponding pin 60, control a different group of the radial levers 52and type-bars 50. The question then of what type-bar shall be impelledwhen the oscillating frame 70 strikes up depends upon (a)-what one ofthe group-controlling levers 65 has its tilting piece in the path ofmovement of the motor-frame 70, and (7)) what position the vibratorypin-carrier occupies, whether its normal position or some one of thepositions into which it is moved re spectively by the depressing of thekeys B, B and B To control the nine tilting pieces 67 67, there are ninekeys C 0, each of which. serves, as we shall soon see, when depressed toswing the tilting piece 67 connected with the group -controlling lever65 that corre-.

sponds to such key over the oscillating frame rangement of the keys andthe parts which they actuate.

The keys B, B and B controlling the pincarrier 61, are designed to beoperated ordinarily and properly by the thumb, while the" nine keys C 0,corresponding to and controlling the diiferent group-controlling levers65 65, are designed to be regularly and properly operated by thefingers. The space-key G is designed to be operated by the ring-finger.

Overlying the keys B, B and B (J C C,and the space-key G is a set ofkey-corresponding and key-actuated levers (which, for greaterconvenience and to distinguish them from the key-levers, I shallsometimes hereinafter term key-actuated levers or key-correspondinglevers) b 11 b 0 c c, and g. These levers are f ulcrumed in front bymeans of a rod 80, which is set in the bar 81. Said bar is milled toreceive the key-actuated levers aforesaid. It serves as a stop to limitthe upward movement of the keys, and it is attached by screws 82 82 tolugs 83 83, that rise from the bed-plate 1.

To the rear end of each of the key-actuated levers b b b 0 cc, and g ishinged a releaser-arm 84, which is held by a contractile spring 85normally in contact with the lug 86 on the metal end piece 87, attachedto the rear end of the corresponding key-lever. (See Figs. 1, 3, and 4.)The releaser-arms 84 84 aforesaid serve each to connect the key-actuatedlever to which it is attached with the corresponding key-lever (B, B orB C G G, or G,) so that when said key-lever is depressed in front by theoperator it rises back of the fulcrum and lifts the correspondingkey-actuated lever through the releaser-arm 84; but about the instantthe type-bar strikes to print-say, preferably, when the type-bar hasmoved about one-fourth to one-third or even less of the distance fromits normal position to the printing-center-the releasing-frame 90, whichis centered at 91 and connected by the link 92 with the arm 93 of themagnetactuated rock-shaft, strikes the releaser-arm 84, moving it off ofthe end piece 87, connected with the key-lever, and allowing all theparts to return instantly to their normal positions and before theoperator has released connected by links 97 97 with the tilting .4 vmars pieces 67 67, serve toconnec't the key-actuI-' when depressedlifts, through the releaser arm 84, the corresponding key-actuated lever0, which serves (a) to swing, through its bell-crank 95 and link 97, thetilting piece 67 connected with the corresponding groupcontrolling leverover the oscillating mo,- tor-frame to receive movement therefrom; (b)to lift the normal frame 140, centered at 141 and which acts on oneof'the bell-cranks 95 aforesaid and through such bell-crankand the link97 connected therewith swingsthe normal tilting piece 67 ofi from overthe 1 motor-frame 7'0, and (c) to lift the circuit-- closing frame 150,centered at 151 and having an arm 152, carrying the battery-connectedspring 153, pressing said battery-connected spring over against thecontact-screw 1541, (to.

which one end of the magnet-coil 79 is connected, theother end of saidcoil being connected with the battery, asshown in Fig. 4,)

thereby closing the circuit of the magnet be-.

fore described, so that the core 76 attractsthe armature 75, whichthereupon lifts the motor.- frame 70, thereby giving movement to what-;ever one of-the tilting pieces 67 overlies it and to thegroup-controlling lever 65 to'which said tilting piece isconnected andto the pin 60 overlying said group-controlling lever. Said pin in turngives movement to Whatever one of the radial levers 52 52 it underlies,and the radial lever thus moved gives movement through the link 56 tothe corresponding type-bar 50, throwing the type up against theprinting-point. As the type-bar approaches the printing ,point thereleasing-frame 9O (centered, as before said, at 91 and connected by thelink 92 with the arm 93 of the magnetactuated rock-shaft 72) strikes thereleaserarm 84, movingit off of the end piece 87, attached to thecorresponding key-lever. Thereupon the key-actuated lever returns to itsnormal position, releasing the various parts controlled by it and, amongothers, releasing the circuit-closing frame 150, which, returning to itsnormal position, breaks the circuitof the motor-magnet aforesaid,whereupon the armature 75, with the oscillating frame 70, return totheir normal positions under the influence of the contractile spring160, releasing the tilting piece 67, group-controlling lever 65, pin 60,radial lever 52, and type-bar 50, all of which immediately return totheirnormal positions, being assisted thereto by suitable springs, someof which are the handas distinguished from the thumb we may properlytermfinger-keys or fingerkey levers) serves when depressed to cause some oneof the type-bars of the group corresponding to itto be actuated by theoscillating motor-frame 70, and if no one of the keys B, B and B (whichfrom the fact that they are designed to be normally and regularlydepressed'by' the thumb we may term thumbkeys or thumb-key levers).is atthe same time depressed that one of the type-bars of the group isactuated whose radial lever 52 over- .lies the corresponding pin 60,when the pinc arr;ier 61 is in its normal position, with the stop 180attached to it, held in contact with the lug 184 of. the stop 182 by thecontractile spring 183. The keys B, B and B serve to oscillate thepin-carrier 61 and thereby to control what one of the type-bars of agroup shall be actuated. For this purpose a pincarrier-driving frame isused, consisting of (a) rock-shaft 170; ((9) three driving-arms 171,

from each other in the pin-carrier'6l, and

each of them controls a group of, four of the radial levers 52 52 andtype-bars 5050. Each pin, as before said, in all its different positionsoverlies the corresponding group-controlling levers 65. Each pinnormally underlies the firstradial lever 52 of the group of radiallevers controlled by it, and it is oscillated to underlie the second,third, and fourth radial levers of its group, respectively, bydedepressing the keys B, B and B respectively. Thus if the key B bedepressed said key gives movement through the releaser-arm 84 to thecorresponding key-actuated lever b, which lifts the stop 17 9, carriedby it, up into the path of movement of the correspondingadjustment-screw 178, carried by the stoparm 177, and at the same timesaid key-actu ated lever bacts, through the push-piece 174, pivoted toit, upon the arm 171 of the rockshaft 170, moving said rock-shaft in thedirection of the arrow, Fig. 1, and through the arm 175 and link 176moves the pin-carrier61 in ,the direction of the arrow, Figs. 7 and 11,so bringing each of the pins 60 60 into operative relation with thesecond radial lever (counting in the direction of the arrow, Fig. 7) ofthe group of radial levers 52 52, controlled by it, in which positionall the parts are arrested by one of the adjustment-screws 178,

carried by the stop-arm 177, coming in contact with the stop 17 9,carried by the key-actuated lever b. If the key B be depressed, thecorresponding key-actuated lever (7 act- IIO ing in like manner throughits push-piece 17 1: upon the arm 172 of the rock-shat't170, moves thepin-carrier 61 until each of the pins 60 60 underlies the third radiallever of the group controlled by it, in which position all the parts arearrested by one of the adjustment-screws 178, carried by the stop-arm177, coming in contact with the stop 179, carried by the keyactuatedlever 11*. If the key-lever B be depressed, the key-actuated lever 17corresponding to and controlled by it acts through 5 its pivotedpush-piece 174 upon the arm 173- of the rock-shaft 170 and through saidrockshaft and its arm 175 and the link 176moves; the pin-carrier 61 inthe direction of the ar-} row, Fig. 7, until the pins 60 60 each under-ilies the fourth one of the radial levers 52 52 l of thegroup controlledby it, in which posi-j tion all the parts are arrested by the stop 180,which is attached to the pincarrier 61, coming in contact with the lug181 of the stop} 182, which stop is screwed fast to the lowerl surfaceof the center ring 40. When the coni nection between the thumb-key leverB, B or B is depressed and the corresponding key- 5 actuated lever 1), bor b is broken by thel action of the motor-impelled releasing-frame 90upon the releasing-arm 84, the pin-carrier i 61 and the parts connectedtherewith are returned by the contractile spring 183 to their normalpositions, with the stop 180, carried by the pin-carrier 61, restingagainst the lug 184 of the stop 182. The pin-carrier 61 is mounted uponan axle 185, set in the cap-ring 55, on which axle it is held by thecollar 186 and a set-screw. (Not shown in the drawings.)

To prevent the motor-magnet from acting to give movement to theoscillating frame while the pin-carrier 61 is taking position, there isa frame 190, Figs. 1 and 4:, centered at 191 and lying underneath thekeys B, B and B so that it is depressed by said keys when acted on bythe operator. The frame 190, Fig. 4c, is connected through thespacemagnet H with one pole of the battery, and it makes connection whenin its normal position with the spring 192, which is connected with thecoil 79 of the motor-magnet. When any of the keys B, B or B isdepressed, the '1 frame 190 impelled thereby moves away from the spring192, breaking connection therewith; but as the key impelling said frameap- I proaches the limit of its movement said frame 1 comes in contactand makes connection with the spring 193, likewise connected with thecoil 79. The frame 190 then, with the springs 192 and 193, serves, itwill be seen, (a) to establish connection between the battery and i thecoil 79 of the motor-magnet when the keys 1 B, B and B are all of themin their normal 1 positions, (1)) to break this connection so soon asany one of said keys begins to be depressed and to keep it broken whilesaid key is be 9 ing depressed and the carrier 61 positioned, and (c) toreestablish the connection as soon as the key B, B or B depressedreaches whatever may be used.

the limit of its movement and the pin-carrier comes'to rest. By thisconstruction the oscillating frame '70 is prevented from striking toimpel a type-bar while the pin carrier 61 is moving into position.

The shift-key, Figs. 1 and 5, is marked 195. It is attached by a stem199 to the frame 196, which isfulcrumed at 197 and connected at 198 by apull-down wire (not shown in the drawings) with one of the bell-crankscarrying the shift-rod (not shown in the drawings) at the top of themachine, by which the platen is shifted, and which being old and wellknown in the art and forming no part of my invention I need not describehere.

The carriage, the ribbon mechanism, the interlinear-spacing mechanism,the alarm-' bell, and other usual details may be of any suitable kind,and as many forms of such devices are well known in the art and as theyconstitute no part of my invention 1 have not thought it best toillustrate them in the drawings or to burden this specification with anydescription of them.

Any suitable form of spacing mechanism I prefer, however, to use aspacing mechanism suchin principle as those illustrated in a number ofprior patents to me, such as the patent of August 8, 1893, No. 502,700,and that of March 1, 1898, No. 600,119, consisting, essentially, of (a)a rack 0 Fig. 14:, suitably connected with the paper-carriage, whichlatter is urged in the direction of the arrow, Fig. 14, by the usualcarriage-motor-spring device (not shown in the drawings) or by any othersuitable means; (19) the fast dog H and the loose dog H (0) thedog-carrying lever H, by which said dogs are vibrated into alternateengagement with the rack e aforesaid; (d) a normal stop H serving,ordinarily, to limit the movement which the loose dog H executes underthe influence of its contractile spring H when withdrawn from the rack 0to a single toothspace of said rack; (e) a space-enlarging lever H towhich said normal stop H is attached, and whereby said normal stop islifted when the space-key G is depressed from its normal position,thereby permitting the loose dog H when freed from the rack c anincreased movement until it is arrested by the stop H attached to thebridle-lever H and (f) means for actuating the dog-carrying lever H.

The key-actuated lever upon which the space-key G acts through thereleaser-arm 84, is connected with the space-enlarginglever H by apush-up H so that whenever the space-key G is depressed it acts throughthe releaser-arm 84, lever g, pushup H, and space-enlarging lever H tolift the stop H thereby to permit an increased movement of the dog Hspacerack c, and paper-carriage connected therewith.

H H are hangers, and H H are stops, Fig. 14, and H is thereturning-spring for the dog-carrying lever H.

C O are the key-levers, toeach of which the releaser-arm 84 is pivoted in front at 111, saidreleaser-arm having a projection 84 formed thereon to be struck in duetime when the'key is depressed by the releasing-frame 90, centered at91. To the releasing-frame 90 is attached an arm B carrying anarmature'100, which lies in the fieldof the electi'ornagnet BA'contractile spring 815 holds the releasing-frame in its normalpositionwith the platinum contactpoint'carried by its arm-B resting againstandmaking connection with a similar contact-point in the adjustmen't-screw 13 The electrical connections of the contact-screw B, thearm B and the electromagnet B are the same as those of thesimilarly-marked parts mine drawings of the Letters Patent aforesaid,No. 604,001, which being fully described in the specification of saidLetters So much Patent need not be further described here.

1 To the motor-frame E is attached an extension 120, to which isconnected a push-piece 121, held in place by guides 122 122. Saidpush-piece serves, as the type-bar impelled by the motor-magnet Eapproaches its printing-point, to strike the releasing-frame 90, movingthe arm B away from the contactscrew B thereby rupturing the circuit ofthe motor-magnet E and permitting the typebar to return instantlyto itsnormal position. lmmediatelyafter thus breaking the circuit of themotor-magnet E the releasing-frame 90, acting on the releasing-arm 84:,releases the key-corresponding lever c, the normal frame 0, and thecircuit-closing frame 18 (both of which are fully described in theLettiers Patent aforesaid) controlled thereby, thereby permitting allthe parts to return to their normal positions.

In thefdevice of Fig. it will be observed the circuit is broken firstwhen the push-piece 121 strikes the releasing-frame 90 by the arm B ofsaid frame moving away from the contact-screw B", with which it isnormally in connection, before the key-actuated lever 0, being releasedby the knocking out of the releaser-arm 84 by the frame 90, allows thecircuit-closing frame 1 8to return to its normal position, and, further,if foranyreason as, for example, when the operator strikes two keys atonce, so that the type-bars are locked on each other and unable to reachthe printing-point, thereby blocking the motorframe E and pushpiece12land preventing them from executing their normal move ments-thereleasing-frame 90 is not moved in due time by the motor-magnet E themagnet B, which is adjusted in any of the ways known toelectricianssuch, for example, as those referred to in the LettersPatent aforesaid, No. 604:,001to besomewhat slower acting than themotor-magnet E attracting the armature 100, attached to the arm B of thereleasing-frame 90, gives movement to said arm and frame, producing theeffects above described that is, breaking the circuit of theelectromaguets and releasing the keycorresponding lever cwhereby all theparts are left free to return-to their normal positions whether the key0 depressed be released or not and whereby the operator is left free toput down asecond key before he has released the first.

Oneiinportant advantage of ,t-hisfeature of myinvention isthemechanical type bar-controlling devices of the kind desimplicitywhich'it gives to the device, as the tage lies in the fact thatthevreleasing is not ef- I fect eduntil an instant of timeafterthekey,whereby another-keymayfbe depressed to print while the keyfirstdepressed is still held down,"has been depressed, thusflea'vingtime for the motor mechanism called-into-action .by the-depressing of}the key to operate;,.. I'am not aware'that any part'operating-in thi'sman- 'nerhassever beenu'sedlin a type-writing machine. The partserving-for this purpose in the structure illustrated in the drawings isthe releasing-frame 90,i np'elled byfithe motor-magnet 79 .butobviouslysomeotherpart than the releasing-frame 190,,i'm p'el'led, -ifirdesired, in (some other :mannerthanbyirneans' of an electromagnet, maybe used instead of said releasing-frame tlO' a'nd magnet-n9 toeffec'tthereleasing; 1 y v v (1)) Another important-feature ofimyinven- ,tion (andone-which, so faras l am zin-forme'd,

erating the releasing mechanism by power other than that exerted uponthekey. Thus in the drawings the releasing-frame 90, which acts upon thereleaser-arm 84, is operated by the magnet 79, Figs. 1 and 4; butobviouslysome other form of motor-operated releasing means might beused, and while I prefer to operate the releasing means by some form ofmotor device I do not, I wish it to be very distinctly understood, limitmyself to the use of a motor device for releasing in any paragraph ofclaim in which a motor device or motor mechanism for releasing is notmade by somesuitable form of'words an express element of the combinationset forth in'such claim.

(d) Another important feature of myinvention (and one which, to'the bestof my information, is broadly new with me) consists in the use of asingle releasing device (whether it be a frame, as 90, or some otherdevice) common to a plurality of latches or other releasable connectionsand serving to free such connections each as required. In the drawingsas already described the common releasing-frame 90 serves to actpositively upon all the releaser-arms 84 84 each as required, thereby torelease all the levers c 0 Z) 17 b g 850., each as required; but while Iconsider it advantageous to use the same releasing-frame or other commonreleasing device to act upon all the releaser-arms 84 or theirequivalents each as required ob-' viously within the broad principle ofmy invent-ion a releasing device may be used to release a plurality ofarms 84 or their equivalents without being used to release the whole setof said arms. In other words, two or more releasing-frames might be usedeach acting upon a plurality of releaser-arms 84: each as required.

(6) Another important feature of myinvention consists in using a singlereleaser-arm, as S4, (or some equivalent part,) for a plurality oftype-bars. The releaser-arm 84, it will be seen, controls mechanismwhich in turn actuates all the type-bars of a. group, each type-bar asrequired, all which, so far as I am informed, is broadly new with me.

(f) Another im port-antfeature of my invention (and one which, so far asI am informed, is broadly new with me) consists in releasing amotor-controlling device to permit the same to return toward its normalposition in advance of the release of the key. In Figs. 1 to 14 the formof motor-controlling device illustrated is the frame 150, controllingthe circuit of the electromagnet 97; but it will be understood that someother suitable form of motor and of motor-controlling device may beused, if desired, and, further, it will be understood that Within thebroad principle of my invention in this regard the motor-controllingdevice may be released by releasing which impels the type-bar or othertype-controlling device. One ad vantage of this is that the point in thetravel of the type-bar or other type-controlling device at which thereleasing is to be effected is readily controlled; but, as has beenalready clearly pointed out, a different motor device may be used tooperate the releasing device from the motor device or motor devices usedto operate the type-bars, matrix-freeing escapement devices, or othertype-controlling devices, whatever these may be. It will be understood,therefore, that when in any of the paragraphs of claim at the end hereofI speak in any form of words of a motor device or of motor mechanism forreleasing without clearly expressing in apt words that said motor deviceis the same motor device which impels a type-bar or the typebars that Ido notlimit myself to the construction in which the motor that releasesis also the type-bar-impelling motor.

(h) It has been proposed heretofore (see, for example, the patent toFlower, No. 426,931,

dated April 29, 1890, and the reissue of the same, No. 11,391, datedNovember 28, 1893,) to connect the key-lever and the correspondingtype-bar together in such manner that when the trip is effected saidkey-lever and type-bar resume their initial positions simultaneously;but in my preferred construction illustrated in the drawings there is noconnection between the key-lever, as B B B C O C, or the key-actuatedlevers, as 1), b b 0, c, c, and g, and the type-bars, whereby either thekey-lever itself and the type-bar (or even the key-actuated lever andthe typebar) are caused to resume their initial positionssimultaneously, and, in fact, the key-actuated lever, having a very muchless distance to travel than the type-bar to return to its initialposition, would naturally resume its initial position before thetype-bar could resume its initial position, and there are reasons alsowhy it is preferable (but not indispensable) that the key-actuatedlevers should resume their initial position without being delayed untilthe type-bars resume their initial positions, and, in fact, I have foundit advantageous in my machines to adjust things in such manner that thereleasing-frame 90 strikes the releaser-arm 84 and efiects the releasewhen the type-bar has moved, say, about one-third the distance(sometimes more and sometimes less) from its normal position to theprinting-point, so that the key-actuated lever, as c, c, f, f*, or fsometimes actually resumes its initial position before they have evenresulted in the production-of are typet'ar liaseveii coiniiie'nced itsreturn movement'and longbefore-it,resnmes its'in drawings and all priordevicesot which I am;
